How to Select a Trailer Hitch
Match Class 3 hardware to the door sticker and the live card before you shop a heavier trailer than the vehicle can honestly tow.
Watch on YouTubeInfiniti FX45 Trailer Hitch Buyer's Guide (Canada)
Shopping a trailer hitch for an Infiniti FX45 in Canada? Start with the door-sticker tow limit on this first-generation crossover, then open the live CURT shelf we stock for listed FX45 years. CURT 13558 is the in-stock Class 3 hitch for two thousand three through two thousand seven FX45 on the live card, sharing that sheet with listed FX35 years. The hitch card rates about three thousand five hundred pounds gross trailer weight and three hundred fifty pounds tongue weight. That is honest light Class 3 hardware for bike racks, small utility trailers, and other light tows that still respect the Infiniti sticker. Door sticker first. Hitch second. Canada orders often ship free on qualifying baskets, so confirm the cart note before you check out.
Parts-counter shortcut.
Start with the door sticker, open the live CURT 13558 card for your FX45 year, then plan lights before the first night tow.

Watch on YouTubeThe live hitch path for listed FX45 years
CURT 13558 is a Class 3 hitch with a two inch receiver path for two thousand three through two thousand seven FX45 crossovers on the live card. The same sheet also covers listed two thousand three through two thousand eight FX35 years. On the hitch card it rates about three thousand five hundred pounds gross and three hundred fifty pounds tongue. That is a modest Class 3 number, so treat the door sticker as the real ceiling even when the hitch tube looks ready for more.
We do not invent a dedicated FX45-only wiring harness promise on this shelf today. Plan a four-flat path and a clean ground after the hitch goes on. Second-generation FX50 and later Infiniti crossovers are separate shopping trips. This page stays focused on the rear receiver path for listed first-generation FX45 years.
